Hi there! Would love to know if there is noticeable lag when playing video games on the projector? I was looking at the VAVA 4k UST and have seen reviews showing lag when gaming, so was wondering about this one as well. Also, would you happen to know if I'd be able to plug this up in the US with a converter?

Thank you!

Yes 100ms is very noticable. I only play slow story-based games on my projector. For fast paced FPS and racing games, I use my LG OLED, which has an amazing response time.

Does anyone know where to find a throw distance calculator? For instance, I'll be using a 90" screen and I'll be placing the unit on top of an existing cabinet. Can I control the image height? How is image size adjusted?

Hei Guys I just got my 3d glasses, the 4k xiaomi projector can accept 3d and its pretty easy set-up, just press the 3 horizontal lines whilst on the movie, hit the display option then the 3d settings will pop up. I've tried a spider man into the spider verse brightness is less brighter compared to an UHD movie but it's bearable and still looks good, no lag and clear so I had to turn the brightness to 100 but everything work perfectly now. When I watched some 3d sbs videos on youtube 3d videos looks amazing in 1080p resolution and clear, but still nothing beats the 4k resolution take note I have projected this on the white wall as I will be ordering a projector screen soon.

Hi, is anyone using a step-up voltage regulator for this projector? In my place, we only have 110 V outlets. If anybody using this projector with a step-up voltage, please suggest which one to buy with specifications.

As I have posted previously in the thread, I cannot get [email protected] straight from my laptop on the projector. The laptop has a gtx 1080 nvidia GPU and it already does [email protected] on my 4k monitor, Wacom Cintiq 24 and also on my TV set with the same cables via HDMI 2.0. After many attempts, 2 new gold plated cables, I managed to enable HDMI 2.0 function on the projector (it was not working properly in the beginning) and SOMETIMES it gets a signal but the picture is flickering badly [email protected] (in my attached pic the image supposed to be plain blue with no lines) . The flickering also happens when I attempt [email protected] but is slightly reduced. I am completely gutted tbh, as [email protected] was the main reason I purchased the projector and used all my economies to purchase it.

I contacted the Chinese re-seller and I got replies like.. I`m trying to use the projector "out of the parameters" set for it and this leads to "unavailability"... more like "trying to use Android 7.0 on a phone designed to use Android 6.0". He concluded the the hardware is fine and good to go! Isn`t this projector advertised as having HDMI 2.0 by Xiaomi? Obviously he won`t accept returns and at this point I have to at lest try everything to make it work. Can somebody help me with some advice?

Many many thanks!

Sorry to hear, nothing worse than some HDMI (HDCP) handshake issues! From my experience, this still sounds like a cable issue: [email protected] requires a lot of 'bandwidth' and even a cable that is 'too long' can't keep up with this. Some other folks like the people behind the HDFury Linker that work a lot with this sort of topic recommend the cable to be shorter than 3m in total AND to be of the highest quality. Sometimes this really is 'hit-and-miss', really.

At this point I`d buy the nVidia Shield if I`d knew is going to work. I have tested 1m, 2m, 3m, 5m cables so far and nothing worked. All those cable don`t have any issues with my monitor, Wacom Cintiq and TV. I have addressed Xiaomi.. but I don`t hold any hopes.

Did anybody tried this with a good laptop/pc? Did you guys managed to get [email protected]?

Hello, I have received the projector as well. Took a couple videos but needs some editing before posting here.

First of all, this beast is amazing ! Bear in mind this is my first projector so I do not have a direct point of comparison, but I'm blown away by the quality and it is projected on my white wall (no screen yet). I can confirm that FPS are not playable with the device. The lag is already noticeable on games like Mario Kart (albait it still is super nice to play the Switch on it and not a big deal for these kind of games).

Main drawbacks for me, not being able to fully translate everything into English, and not having native Netflix / Play Store, but those are minor issues.

Did not test 3D yet, if someone can point me to a pair of glasses that should work I'll order them and test on 4k blu-rays.

If you can't find the YouTube video drop me private message and I will send you the link.

How decent is the picture in daylight?

Hey ! Issue is the APK I found was for the older models / I'm kinda afraid to download it. Most of the stuff work with the native translation setting so I won't risk it for now.

As for daylight - I live in a very bright place with a lot of direct sunlight. During the day there is not much the projector can do unless I dim the room by rolling down my shutters ~half way. I'll post pictures soon if you want, comparing night / day / dim room. Bear in mind I have no screen installed (yet).

A small update. I connected my ps4 pro, launched youtube and activated "stats for nerds". [email protected] clips are working without problems. I wonder why from my laptop it cannot.

Would this have anything to do with your laptop outputting 4k60 4:4:4 and your PS4 outputting 4:2:0 or 4:2:2? I’m not too familiar with chroma but I do know one uses more bandwidth than the other and not all devices can display 4:4:4.

We are looking to order tab-tensioned projector screen from China for UST Xiaomi 4K projector, the projector is produced by XY a Chinese manufacturer. Would like some opinion from you guys. We would given the below project screen spec where we plan to order for around $600USD for 120 inch tab tensioned motorized version.

We are placing it on a window and i know the screen needs to be in dark room. So we can have the curtain closed when watching movies.
What do you guys think of this screen when compared to other more expensive options like cinetension cinetension 2 from elitescreen? and is this a good screen or the setup ideal if i can close the curtain and the room is dark?

Hi, i am new around her and from the UK but there aren't many places where people ahve bought the new 2019 laser projector so thought i'd ask here.

I'm looking at buying the new 2019 4K version and from what i am led to believe it is only avialable in chineese but seems easy enough to install the english menus.

I currently have a sonos palybase and 2 x Play 1's for surround sound and plan on using the optical output for those

My usage would be Apple tv4k, the caveat to that is it is all done via plex media server so reliant on what the uploaded files are but they are very rarely 4k and more 1080 at best.

I use IPTV streaming services and again very rare i would get the true 4k output

Xbox one S for gaming, mostly fortnite if i am honest for my son with the odd UHD movie. Would be nice to add a 3D player and make use of the 3D from time to time and buy the relevant glasses.

Other than gaming during the day mostly watch tv on an evenings but wondered if it needs to be complete darkness during the day or if closing the blinds is acceptable during the day ?

Given my use is this over kill for what i need but also is there a better option for me ? I am looking at buying it for around 1600 pounds (2079 dollars) and then import duty and vat at 550 pounds (715 dollars) so not a cheap purchase and want it to be as future proof as possible
